SPIRIT-LEVEL.

SPECIFICATION forming part of Letters Patent No. 676,330, dated June 11, 1901.

Application filed March 27,1901. Serial No. 53,092. (No model.)

To @ZZ whom it' may concern;

Be it known that I, JACOB LEMLE, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented a new and useful Spirit-Level, of which the following is a speciiication.

The invention relates to improvements in spirit-levels.

The object of the present invention is to improve the constructionof spirit-levels, more especially the manner of mounting the level glass or vial, and to enable the latter to be readily adjusted vertically from the exterior and to cushion the same.

The invention consists in the construction -and novel combination and arrangement of Like numerals of reference designate cor-V respondiugpartsin all the figures of the drawings.

1 designates a rectangular frame receiving a level-glass or bubble-vial 2 and adapted to be mounted in the usual manner on a level 3, as clearly illustrated in Figs. l and 2 of the accompanying drawings; but it will be read ily understood that the improvements are adapted to be applied to plumbs and other tools. The rectangular frame 1, which is mounted in a recess of the level 3, is provided at its top with a sight-opening 4, and it has a circular aperture 5 at one end to receive one end of the bubble glass or vial and a cushion lfor supporting the same. The cushion 6, which may be of any desired construction, is cylindrical land surrounds the adjacent end of the level glass or vial. The other end of the level glass or vial is arranged within a vertically-adjustable support or hanger 7, consisting of a rectangular loop and a stem S, 'extending upward from the loop and arranged in an opening or socket 9 of the top of the frame 1, as clearly shown 'in Figs. 2 and 3 of i the drawings. The rectangular loop of the hanger or support7 receives a cushion 10, of

rubber or other suitable material, provided with a circular opening for the reception of the adjacent end of the level glass or vial. By cushioning the level glass or vial in this manner the tool may be handled more or less carelessly without liability of breaking the said glass or vial. The stem, which extendsA upward in the opening or socket 9 of the frame l, is engaged by a clamping-screw 1l, which holds the hanger or support at any desired adjustment. By loosening the clamping-screw the hanger or support may be raised or lowered, and by tightening it the level glass or vial will be secured at the desired adj ustment.

The frame 1 is covered by top and side plates, the top plate l2 being provided with an opening 13, corresponding with the sightaperture 4 and adapted to permit the level glass or vial to be readily seen from the top. The side plates 14 and l5 are provided with apertures 16 to enable the level glass or vial to be seen from the side, and the side plate 14 is provided with upper and lower openings 17 and 1S, the upper opening 17 being located opposite the clamping-screw and being adapted to permit a screw-driver to be readily introduced into the level for the purpose of manipulating the screw. The lower opening 18 is located opposite a notch 19 of the loop of the hanger or support, and itpermits a screw-driver or other tool to be interlocked with the hanger or support,whereby the latter may be raised and lowered to set the level glass or vial in proper position. After the level glass or vial is properly adjusted the clamping-screw is tightened. The side plates are shown segmental in Fig. l; but when the device is mounted on a plumb or other tool at a point between the edgesof the same the side plates may be circular and the top plate may be omitted.

1t will be seen that the spirit-level is eX- ceedingly simple and inexpensive in construetion; that it is effectively cushioned, and that it is capable of adjustment from the exterior and at one side, so that the adjustment or adjusting devices will not interfere with the arrangement of the level glass or vial at any point on a tool, either at the edge of the same -or between the edges thereof.

IOO

combination of a glass or Vial, a frame pro# vided with an opening receiving one end of the glass or vial, said frame being also provided at its top with an opening or socket, a hanger or support having a loop receiving the other end of the glass or vial, said hanger or support being provided with a stem fitting in the said s0cket\or opening, a clamping-screw mounted on the frame and engaging the stern, and a side plate having an aperture arranged opposite the clamping-screw, substantially as described.

a 3. Inv a device of the class described, the combination of a frame provided at one end with an opening and having a socket or opening at the top, a hanger or support fitting in the socket or opening and provided With a lower loop having a notch, a level glass or vial arranged in the end opening of the frame and in the loop of the hanger or support, a clamp- V ing device mounted on the frame and engaging the support or hanger, and a side plate having apertures located opposite the notch and the clamping device, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two Witnesses.

JACOB LEMLE.
